Do you own a Crucible ? Do you like it and would you recommend owning one and a couple of Kingsley Pre amps ?Using the preamps FOA yields very different results than using them as actual preamps. The effect will be much less prevalent, and you won’t be unlocking their full capability.
As to point #1, running different preamps FOA doesn’t magically give you a choice of different amps. It just kind of gives you a few different flavors of EQ curves and perhaps mild gain. You can’t achieve the same levels of OD with a preamp pedal FOA that you can used as an actual preamp. So if you’re looking for that Marshall crunch, the Constable FOA won’t get you there. It needs to be used as an actual preamp.
I run a squire FOA, but I use it as an EQ. I switch between the D and the BF. They work great, but they are subtle and subtly different. They don’t magically turn my amps into a dumble or fender. They just help to sculpt the tone.
Having tried most of the preamps FOA, I’d start a Kingsley journey with his ODs if you’re only planning on running his stuff FOA. You’ll get more satisfying results and you’ll better understand why everyone here loves his stuff.
If you like the ODs, you might dabble in some preamps FOA. But you’ll have to understand you’re not fully unlocking their power by doing so.
As to which he is more known for, that’s a tough question. I think the ODs are second to none and there is very little out there up to the quality. But the OD market certainly isn’t lacking for choice.
His preamp pedals, though, are unique and in a way groundbreaking. More and more companies are headed that way, but what he is offering with these pedals is exact replicas Of very famous preamps. Others are starting to do that, but Simon is way ahead of the game, and without a dip in quality.
However, despite the members of this thread, I’d still say there is more demand for straight ahead OD pedals.
